An example method of authenticating a user includes receiving, by a merchant application, a user request to complete a transaction using a payment service provider. The method also includes in response to receiving the user request to complete the transaction, retrieving, by the merchant application, a browser cookie stored on a user device and associated with one or more user interactions with a browser included in the user device and the payment service provider. The method further includes in response to receiving the user request to complete the transaction, launching, by the merchant application, an instance of the browser that reads the browser cookie and authenticates the user based on the browser cookie.

CROSS REFERENCE TO RELATED APPLICATIONS

The present application is a continuation application of U.S. patent application Ser. No. 15/141,543, filed Apr. 28, 2016, and is incorporated in reference in its entirety.

BACKGROUND Field of the Invention

The present disclosure generally relates to systems and methods for authenticating a user.

Related Art

More and more consumers are purchasing products and services over electronic networks such as, for example, the Internet. Consumers routinely purchase products and services from merchants and individuals alike. The transactions may take place directly between a conventional or on-line merchant or retailer and the consumer, and payment is typically made by entering credit card or other financial information. Transactions may also take place with the aid of an on-line or mobile payment service provider such as, for example, PAYPAL®, Inc. of San Jose, Calif. Such payment service providers can make transactions easier and safer for the parties involved. Purchasing with the assistance of a payment service provider from the convenience of virtually anywhere is one main reason why on-line and mobile purchases are growing very quickly.

Before a payment service provider renders services to a user, the payment service provider will typically request the user's user credentials in order to authenticate the user. It may be inconvenient for the user to provide her user credentials to the payment service provider each time she desires to use the services of the payment service provider, especially if the user uses the payment service provider quite often. Additionally, nowadays, users typically have multiple accounts with different websites. For each website, the user has a username and password to remember. Accordingly, it may be inconvenient for the user to remember her username and password for the payment service provider.

Additionally, many payment transactions enabled by online or mobile payment service providers such as, for example, retail purchases, payment transactions, and the like, are made electronically using electronic devices, such as mobile phones or mobile computing devices. For example, a consumer may install a payment application provided by the payment service provider on his or her mobile device to facilitate payments to various merchants or recipients. An online or mobile payment process utilizing the payment application typically includes user authentication that requires a user to enter a login identifier (ID) and/or a password to authenticate the user. Nevertheless, the authentication process may cause inconvenience to the user especially if the user is in a hurry or if a keyboard is not included with the mobile device for the user to type in the login ID or password. As such, the authentication process may delay the overall payment process and cause the payment process to take longer than making a payment with cash, which can discourage the use of online or mobile payments. Therefore, there is a need for a system or a method that implements an easier authentication process on user devices.

DETAILED DESCRIPTION

A user may use a user device to access a merchant application and desire to purchase products and/or services (e.g., collectively referred to as items) provided by a merchant via the merchant application. In an example, the merchant application is a mobile app installed on the user device. In another example, the merchant application is a web application accessible via a uniform resource locator (URL) to which a browser executing on the user device points. The user may interact with the merchant application to purchase items by placing them into an electronic shopping cart provided by the merchant application. Additionally, the merchant application may provide the user with the option to complete the purchase (or any transaction) using an account the user has with a payment service provider.

Typically, if the user requests to complete a transaction using the payment service provider while interacting with a merchant application, the merchant application directs the browser executing on the user device to the payment service provider's website for authentication purposes. A payment provider server managed by the payment service provider may request the user to enter her user credentials and authenticate the user based on the entered user credentials. An authentication service may provide an authenticated login session to the user via the user device and allow the user access to services provided by the payment provider server if the user is authenticated. If the user is successfully authenticated, the payment provider server provides the user device with a browser cookie and an access token to access the services of the payment provider server. The browser may receive the browser cookie from the payment provider server and store it in a browser memory. The browser cookie may include a refresh token, which allows the user device to obtain fresh access tokens from the payment provider server (e.g., secure token service) without having to enter user credentials. As such, it may be unnecessary for the user to enter her user credentials in order to obtain an access token and thus access resources provided by the payment provider server.

The present disclosure provides techniques for the merchant application to authenticate the user by accessing the browser cookie stored in the browser memory and without the user being prompted to enter her user credentials. While in the merchant application, if the user attempts to purchase items and requests to complete a transaction using the payment service provider, the merchant application accesses the browser cookie that was previously received from the payment provider server and stored in the browser memory, launches an instance of the browser, and passes the browser cookie to the browser instance. The browser instance may perform further actions to authenticate the user, without the user being requested to enter her user credentials. Accordingly, if the user requests to complete a transaction with the payment service provider while in the merchant application, it may be unnecessary for the user to sign in and provide her user credentials to the payment service provider. Rather, if the refresh token is still “alive” on that same user device (e.g., cookie has not yet expired and cookie's value is valid), the payment provider server may authenticate the user without the user being prompted to enter her user credentials. In this example, the payment provider server that is maintained by the payment service provider skips the request for a user login and subsequent receipt of user provided login information, and instead authenticates the user based on information stored in the browser cookie. In this way, the user may be authenticated by the payment service provider without being prompted to provide her user credentials for the current session.

If the user is successfully authenticated, the payment provider server provides the user device with a new access token for accessing services provided by the payment service provider. Accordingly, the user may complete transactions using an account the user has with the payment service provider while still in the merchant application, without having to provide her user credentials to the payment provider server. Additionally, the user may complete transactions using an account the user has with the payment service provider on different merchant applications or websites, without having to provide her user credentials to the payment provider server. Accordingly, the user may enjoy the experience of not having to enter her user credentials and may be provided with a more streamlined experience.

Unless specifically stated otherwise, as apparent from the following discussion, it is appreciated that throughout the description, discussions utilizing terms such as “receiving”, “sending”, “storing”, “providing”, “generating,” “determining”, and “authenticating”, “retrieving,” “launching,” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.

A user may interact with a merchant application. FIG. 1 is an example page 100 that is displayed by the merchant application on a display of a user device 102. Page 100 includes content that may be controlled and provided by the merchant. In the example illustrated in FIG. 1, page 100 includes one or more items 102 that are provided by the merchant and included in a user's electronic shopping cart 104 provided by the merchant application. The user has two items 102 in electronic shopping cart 104, as indicated by a number in a circle 106.

Page 100 also includes user selectable options that if selected by the user cause particular actions to be performed. The user may select a user selectable option 110, which is labeled “Remove,” to remove the items displayed on page 100 from electronic shopping cart 104. Alternatively, the user may select a user selectable option 112, which is labeled “Continue Shopping,” to view other item(s) offered by the merchant application. In response to the user selecting user selectable option 112, the merchant application may display one or more items provided by the merchant that the user may place into electronic shopping cart 104 for purchase. The user may then proceed to place items into electronic shopping cart 104. Alternatively, the user may select user selectable option 114 to check out with a payment service provider and complete the transaction using the payment service provider, with the items currently in electronic shopping cart 104. In response to the user selecting user selectable option 114, the merchant application may receive the user's request to complete a transaction using the payment service provider.

FIG. 2 is a flowchart illustrating an embodiment of a method 200 of a merchant application using a browser cookie stored in the browser memory to authenticate a user. Method 200 is not meant to be limiting and may be used in other applications other than the applications discussed below. Method 200 includes blocks 202, 204, and 206.

In a block 202, a merchant application receives a user request to complete a transaction using a payment service provider. The user may send the request to the merchant application to complete the transaction in a variety of ways. In an example, the merchant application provides a “Checkout with Payment Service Provider” button that if selected by the user sends a request to the merchant application to complete the transaction using the payment service provider (see user selectable option 114 in FIG. 1). In another example, the merchant application provides a “Confirm Payment” button that if selected by the user sends a request to the merchant application to complete the transaction using the payment service provider (see user selectable option 914 in FIG. 9).

In response to receiving the user request to complete the transaction using the payment service provider, blocks 204 and 206 may be executed. In block 204, in response to receiving the user request to complete the transaction using the payment service provider, the merchant application retrieves a browser cookie stored on the user device and associated with one or more user interactions with a browser included in the user device and the payment service provider. A browser cookie is a small text file that allows a website or web application to recognize a particular user and their interaction(s) with the website or web application. The browser cookie may have been previously sent to the browser by a payment provider server operated by the payment service provider and saved by the browser into the browser memory.

FIGS. 3-5 will be discussed in conjunction with each other to better explain the user's previous interactions with a browser 302 included in the user device and a payment provider server 304. Swim diagram 300 includes actions 306, 308, 310, and 312, which may have occurred before the execution of blocks 202, 204, and 206 in FIG. 2.

FIG. 3 is an example swim diagram 300 illustrating user interactions that provide the browser with the browser cookie that is retrieved by the merchant application in block 204 in FIG. 2. In FIG. 3, at an action 306, browser 302 sends payment provider server 304 a user request 307, which may be a user request to complete a transaction using a payment service provider. The user may be a consumer and may use user device 102 to complete a transaction using payment provider server 304. Payment provider server 304 is a server that is remote from user device 102. Payment provider server 304 may be maintained, for example, by an online payment service provider that provides payment between the user and the merchant that maintains the merchant application. Payment provider server 304 may be maintained by a payment service provider, such as PAYPAL®, Inc. of San Jose, Calif. Payment provider server 304 may be configured to interact with user device 102 and/or a merchant that maintains the merchant application over a network to facilitate the purchase of goods or services, communicate/display information, and send payments by the user of user device 102 to a third-party (e.g., the merchant).

It should be understood that payment provider server 304 may represent one or more payment provider servers that are provided by the payment service provider. Although the description may provide examples in which payment provider server 304 performs actions, it should be understood that servers executing on different computing devices may perform these actions. For example, a first payment provider server 304 (e.g., payment provider server 304 a) may perform a first action and a second payment provider server 304 (e.g., payment provider server 304 b) may perform a second action.

Browser 302 may send, based on a variety of inputs from the user, user request 307 to payment provider server 304. FIG. 4 is an example webpage 400 including a user selectable option 408 that if selected by the user causes browser 302 to send user request 307 to payment provider server 304. Webpage 400 is a webpage that is controlled by and provided by a second merchant that may be the same as or different from the merchant that controls the merchant application that displays page 100 in FIG. 1. Additionally, the merchant application controlled by the second merchant may be the same as or different from the merchant application that displays page 100 in FIG. 1. Browser 302 may display webpage 400 on a display of user device 102. Payment provider server 304 may send browser 302 webpage 400 for display on user device 102.

Content of webpage 400 is referenced by a URL 402, which is “www.secondmerchant.com/confirmpay,” and includes the user's selected item(s) along with the price and various ways for the user to pay for those item(s). For example, webpage 400 includes the option to pay with a credit card via user selectable object 404, debit card via user selectable object 406, or a user account the user has with a payment service provider via user selectable object 408. The user's user account with the payment service provider is linked to one or more methods of payment, which may include the user's credit card, debit card, bank account (e.g., checking account), and/or other forms of payment, etc. to which the user has given the payment provider server permission to access. The user may select one of these options by selecting the appropriate user selectable object and selecting a user selectable object 410, which is labeled “Enter.”

If the user selects user selectable object 404 to pay with a credit card, the user may be provided with a prompt to enter credit card information. If the user selects user selectable object 406 to pay with a debit card, the user may be provided with a prompt to enter debit card information. If the user selects user selectable object 408 to pay with a payment account linked to the user's payment service provider user account, the merchant application provided by the second merchant may redirect the user device to payment provider server 304. In response to the user selecting user selectable object 408 shown in webpage 400 in FIG. 4, browser 302 may send user request 307 to payment provider server 304. The user request may also include details of the transaction such as the total amount of the transaction, item(s) purchased, etc. Payment provider server 304 may receive user request 307, which may be a user request to complete the transaction using the payment service provider.

Referring back to FIG. 3, at an action 308, in response to user request 307, payment provider server 304 sends browser 302 a login webpage 309. Browser 302 receives login webpage 309 and displays it on a display of the user device. Before payment provider server 304 allows the user to access resources stored or protected by the payment provider server, it may prompt the user for her user credentials via login webpage 309 and authenticate the user.

FIG. 5 is an example login webpage 309 that is provided by payment provider server 304 to the user device. Payment provider server 304 may provide webpage 309 in response to the user selecting user selectable object 408 to pay with the user's payment account linked to the user's payment service provider user account (see FIG. 4). Webpage 309 is referenced by a URL 502, which is “www.paymentserviceprovider/login.com,” and is controlled by and provided by the payment service provider. Browser 302 displays webpage 309 on a display of user device 102. Browser 302 initially displayed web content from a second merchant in FIG. 4 and has now transitioned to displaying web content from payment provider server 304 in FIG. 5. In this example, the selection of user selectable option 408 displayed on webpage 400 may redirect browser 302 executing on the user device to point to the payment provider server. Webpage 309 is a login page including a prompt 504 that requests the user to enter her user credentials (e.g., a username and password) into the login webpage for authentication purposes. The user may enter her user credentials into the login webpage and select a user selectable option 506, which is labeled “Submit,” to submit her user credentials to the payment provider server for authentication purposes. If the user desires to be remembered by the payment service provider and to opt in for faster payments, the user may select a user selectable option 508. In the example illustrated in FIG. 5, the user has opted to be remembered by the payment service provider. In response to the user selecting user selectable option 508 and user selectable option 506, the payment service provider may “remember” the user and streamline her payment experience, which may include the payment service provider authenticating the user without requesting the user's user credentials. By selecting the selectable option 508, the user may opt into a “one touch” feature provided by the payment service provider, which allows the user to request from a merchant application that a transaction be completed using the payment service provider once and authenticating the user without requesting her user credentials. Accordingly, in some cases, payment provider server 304 provides the user with the ease of not having to remember her user credentials and entering them into a login page provided by the payment provider server 304. Users typically have accounts with multiple websites and opting into the “one touch” feature may provide the user with a more streamlined experience of interacting with merchant applications and purchasing items. Payment provider server 304 may store the user's request to be remembered by storing a refresh token in the browser cookie that is sent to the user device, as will be discussed further below.

Referring back to FIG. 3, at an action 310, browser 302 sends the user's user credentials (e.g., the user credentials entered into webpage 309) to payment provider server 304. Payment provider server 304 receives the user's user credentials and may proceed to perform actions to authenticate the user. The payment provider server may include or interact with an authentication platform 311 that receives the user's user credentials and determines, based on the entered user credentials, whether the user has been successfully authenticated. At an action 312, payment provider server 304 sends the user credentials to authentication platform 311. At an action 314, authentication platform 311 searches an authentication database 316 that stores user credentials (e.g., usernames and passwords) that have been registered with the payment service provider. In an example, authentication platform 311 makes a call to/v1/OAuth/login in order to effectively login the user and obtain an access token. Parameters of the call may include the user's login credentials.

At an action 318, if authentication platform 311 successfully authenticates the user, authentication platform 311 sends a browser cookie 319 to browser 302. A browser cookie is a small text file that allows a website or web application to recognize a particular user and their interaction(s) with the website or web application. Accordingly, if payment provider server 304 or another payment provider server that is operated by the payment service provider receives browser cookie 319 at a later point in time, the payment provider server may recognize the user and identify her information. In some examples, browser cookie 319 is a data file that stores session information regarding the user's interactions with the payment provider server (e.g., the transaction along with its details), the user's preferences, and/or a refresh token. The refresh token provides an expiration date for the browser cookie (e.g., 60 days from date of issuance). In some examples, the refresh token is encrypted.

A refresh token represents the authorization granted to the client by payment provider server 304. In some embodiments, the refresh token may be a string. The string may be opaque to the client. The refresh token is a representation of the logged-in user and in some examples may be a credential used to obtain an access token. The refresh token denotes an identifier used to retrieve the authorization information. In some examples, the refresh token is issued to the client by authentication platform 311 and is used to obtain one or more new access tokens when the current access token becomes invalid or expires, or to obtain additional access tokens with identical or narrower scope. For example, access tokens may have a shorter lifetime and fewer permissions than authorized by the payment provider server 304. Authentication platform 311 may generate the access token without requesting the user to enter the user's user credentials.

Authentication platform 311 may perform additional checks before generating and sending an access token to the user device. In some examples, browser cookie 319 includes an indication that the user has opted into the “one touch” feature provided by the payment service provider. In an example, browser cookie 319 includes a refresh token, which indicates that the user has opted into the “one touch” feature. In some examples, refresh token 622 is passed along with a request for one or more authorization scopes (e.g., valid access to downstream services) to authentication platform 311. Authentication platform 311 may check for the validity of refresh token 622 (e.g., if the refresh token has not yet expired) and if each of one or more the authorization scopes can be granted on the refresh token, authentication platform 311 sends an access token to the user device. The access token may then be passed to a resource server (e.g., payment provider server 304) to request one or more resource(s) from the resource server. In this example, without a valid access token, the request to the resource server fails.

Browser 302 receives browser cookie 319 and stores it in a browser memory on the user device. In some examples, payment provider server 304 and authentication platform 311 are included and executed in the same computing device. For example, authentication platform 311 may be incorporated in payment provider server 304. In some examples, payment provider server 304 and authentication platform 311 execute on different computing devices.

In some examples, authentication platform 311 may include a secure token service. If the user has been successfully authenticated, the secure token service may generate an access token and provide it to the user device. The secure token service may provide an inspection and validation of browser cookies based on policies and may drive the assessment of browser cookies (e.g., refresh tokens, etc.) to determine whether they are sufficient for a login. An access token is a data object by which a client authenticates to a resource server (e.g., payment provider server 304) and lays claim to authorizations for accessing particular resources. For example, the user device may use an access token generated by the payment provider server to access a resource (e.g., user account and payment account information) provided by the payment provider server. The payment provider server may then provide the user device with an authenticated session and complete the transaction.

Payment provider server 304 may provide the user device with a refresh token that is used to keep the user logged into the payment provider service system. In an example, the payment provider server generates a refresh token and provides the user device with a browser cookie that includes the refresh token. The browser cookie may have an expiration date (e.g., 60 days from the date of issuance). As long as the browser cookie has not yet expired, the user may perform other transactions (e.g., payments via the payment provider server) without having to login and provide her user credentials.

The user device may receive the browser cookie and store the browser cookie including the refresh token into the browser memory. The refresh token keeps the user “alive” across refreshes and across webpages as long as the browser cookie has not yet expired. The browser cookie that is placed in the browser memory allows a secure token service to determine scenarios where a full login (e.g., entering user credentials) can be skipped. Accordingly, it is this browser cookie sent from payment provider server 304 to browser 302 that the merchant application that provides page 100 in FIG. 1 may retrieve from the browser memory in response to later requests by the user to complete a transaction using the payment service provider. The browser cookie that is retrieved by the merchant application can be used to authenticate the user, without requesting the user to enter her login credentials.

Alternatively, if the user has not been successfully authenticated based on the user credentials, payment provider server 304 send a message indicating that the user has not been successfully authenticated to the user device. In an example, payment provider server 304 may send this message to browser 302 for display on the user device along with a prompt for the user to enter her user credentials again.

Although in the example illustrated in FIG. 3, browser 302 is shown as sending user request 307 and the user credentials entered into login webpage 309 to payment provider server 304, this is not intended to be limiting and it should be understood that a mobile application installed on user device 102 may perform these actions. In this example, the mobile application may point to payment provider server 304 and interact with the payment provider server 304 to perform actions 306 and 310. If the user is successfully authenticated, authentication platform 311 may send browser cookie 319 to user device 102. Browser 302 may receive browser cookie 319 and store it in the browser memory for later retrieval by browser 302 or a mobile application installed on user device 102.

In an example, a merchant application passes control to an associated Software Development Kit (SDK) provided by the payment service provider to retrieve the browser cookie. An SDK includes a set of tools and platform components (e.g., set of software libraries) for developers to develop, build, test, debug, and optimize their applications, and manage the platform component installation. The SDK may also provide easy ways to integrate with the build and development environments. In an example, the SDK is PAYPAL TOUCH®, available from PAYPAL® Inc., of San Jose, Calif., and the payment service provider is PAYPAL®, Inc. of San Jose, Calif. However, a variety of entities may provide the SDK and operate as the payment service provider.

An SDK may be provided by a payment service provider to the merchant that maintains the merchant application. The merchant may incorporate the SDK into the merchant application during the building of the application. In an example, if a user downloads the merchant application on a user device, the SDK may also be downloaded with (or as part of) the merchant application on the user device. As such, when the user selects the merchant application by, for example, selecting an icon associated with the merchant application, the merchant application (along with the SDK) is launched. In another example, the SDK may be part of an application that is trusted by the payment provider server and that interacts with the merchant application on the user device. In such an example, the user may download the SDK independent of the merchant application for execution on the user device.

The SDK communicates with a payment provider server (e.g., payment provider server 304) operated by the payment service provider and sends information to and receives information from the payment provider server. In an example, the SDK and the payment provider server may communicate with each other to authenticate the user. In some examples, the SDK provides the user selectable option (e.g., user selectable option 114, which is labeled “Checkout with Payment Service Provider)” that if selected causes the merchant application to retrieve the browser cookie associated with one or more user interactions with browser 302 and the payment service provider.

The user device may include a plurality of merchant applications, each of which may incorporate the SDK from the payment service provider. Accordingly, any one of these merchant applications may access the browser cookie stored in the browser memory and perform actions to authenticate the user.

Referring back to FIG. 2, in block 206, in response to the user request to complete the transaction using the payment service provider, the merchant application launches an instance of the browser that reads the browser cookie and authenticates the user based on the browser cookie. In some examples, in response to receiving the user request to complete the transaction using the payment service provider, the merchant application causes a browser instance to be launched on the user device and provides the browser instance with the browser cookie retrieved from the browser memory. The browser instance may be an instance of a browser that is installed on the user device, may include features of the browser, and may share browser cookies and other website data with the browser. In some examples, the user's activity and interaction with the browser instance are not visible to merchant application(s). In an example, merchant application(s) cannot access the user's browsing history or website data.

It should be understood that additional processes may be performed before, during, or after blocks 202, 204, and/or 206 discussed above. It is also understood that one or more of the blocks of method 200 described herein may be omitted, combined, or performed in a different sequence as desired.

FIG. 6 is an example process flow of a networked system 600 configured to implement a process for authenticating a user. Networked system 600 may include or implement a plurality of servers and/or software components that operate to authenticate a user and/or perform various payment transactions or processes. Exemplary servers may include, for example, stand-alone and enterprise-class servers operating a server operating system (OS) such as a MICROSOFT® OS, a UNIX® OS, a LINUX® OS, or other suitable server-based OS. It can be appreciated that the server(s) may be deployed in other ways and that the operations performed and/or the services provided by such a server may be combined or separated for a given implementation and may be performed by a greater number of servers. One or more servers may be operated and/or maintained by the same or different entities.

FIG. 6 includes user device 102 coupled to a network 608. Network 608 may include various configurations and use various protocols including the Internet, World Wide Web, intranets, virtual private networks, wide area networks, local networks, private networks using communication protocols proprietary to one or more companies, cellular and other wireless networks, Internet relay chat channels (IRC), instant messaging, simple mail transfer protocols (SMTP), Ethernet, WiFi and HTTP, and various combinations of the foregoing.

User device 102 includes browser 302, a merchant application 604, and a browser cookie 319. In the example illustrated in FIG. 6, merchant application 604 may be installed on user device 102. The user may have downloaded merchant application 604 on user device 102 or may have received this application already downloaded on user device 102. Merchant application 604 may be maintained, for example, by a merchant or seller offering various products and/or services. The merchant may be a participating merchant who has a merchant account with the payment service provider. Generally, a merchant server may be maintained by anyone or any entity that receives money, which includes charities as well as retailers and restaurants. For example, a purchase transaction may be a donation to charity.

In some examples, user device 102 is a mobile device (e.g., smartphone or computing tablet), and the user downloads one or more mobile applications onto the mobile device. A mobile application may be a merchant application that communicates with a merchant server. In an example, user device 102 is an ANDROID® device that is installed with the ANDROID® mobile OS. A mobile application is a software program that may be downloaded and accessed directly via the mobile device. A mobile application may be represented by an icon on a display of user device 102, and the user may select the mobile application by touching a location on the display of the device corresponding to the icon (e.g., double tapping the icon) to access and interact with the mobile application. In some examples, user device 102 is a desktop computer, and the user points the browser executing on the desktop computer to a merchant server in order to retrieve webpages controlled by the merchant or points the browser to a payment provider server in order to retrieve webpages controlled by the payment service provider.

Merchant application 604 includes an SDK 612. Although user device 102 is illustrated as including two applications (e.g., merchant application 604 and browser 302), this is not intended to be limiting and user 102 may include more than two applications. For example, user device 102 may include another merchant application that also includes SDK 612. Additionally, although the description may provide examples of merchant application performing particular actions, it should also be understood that SDK may perform these particular actions. Browser 302 may receive browser cookie 319 from payment service provider 304 as discussed relative to FIG. 3 and store the browser cookie into the browser memory. As discussed above relative to FIG. 2, in response to a user request to complete a transaction using the payment service provider, merchant application 604 may retrieve browser cookie 319 and launch an instance 614 of browser 302. Merchant application 604 may provide browser cookie 319 to browser instance 614, which reads the browser cookie and authenticates the user based on the browser cookie.

Browser instance 614 may be loaded with a reference to content (e.g., uniform resource locator (URL)). The reference may point to resources stored at payment provider server 304. In the example illustrated in FIG. 6, merchant application 604 (or SDK 612) launches browser instance 614 that references a URL 616 hosted by payment provider server 304 or another payment provider server operated by the payment service provider. Merchant application 604 may pass payment details of the transaction (e.g., item(s) and/or and total amount of transaction) and browser cookie 608 to browser instance 614 for authenticating the user.

URL 616 may reference a façade 620, which includes a web application hosted by the payment service provider and stores content of URL 616. Façade 620 may read browser cookie 319 and determine whether it includes a refresh token 622. If browser cookie 319 does not include a refresh token, then façade 620 may redirect the user to login webpage 309 (see FIG. 5). If browser cookie 319 does not include a refresh token, the user may have indicated to the payment service provider that the user does not wish to opt into the “one touch” feature. In this example, the user may desire to provide her user credentials to the payment service provider before accessing resources of the payment service provider (rather than being authenticated based on the browser cookie).

If browser cookie 319 includes refresh token 622, façade 620 may send the refresh token to authentication platform 311. Authentication platform 311 determines whether refresh token 622 is valid. Authentication platform 311 may determine that refresh token 622 is valid if the browser cookie associated with the refresh token has not yet expired. Conversely, authentication platform 311 may determine that refresh token 622 is not valid if the browser cookie associated with the refresh token has expired. In response to determining that refresh token 622 is not valid, authentication platform 311 may redirect the user to login webpage 309 (see FIG. 5). In response to determining that refresh token 622 is valid, authentication platform 311 generates an access token 626 and sends the access token to façade 620.

Façade 620 may receive access token 626 and send it to a checkout platform 627 that stores the user's financial information associated with the payment service provider. For example, the user's financial information may be associated with a user account the user has with the payment service provider. Access token 626 may allow the user to access the services of the payment service provider to complete a transaction. Checkout platform 627 searches a database, identifies the user's financial information 628, and sends the user's financial information 628 to façade 620. Façade 620 receives the user's financial information 628 and provides checkout information 630 to user device 102. SDK 612 may receive checkout information 630 and renders the appropriate checkout information on a display of user device 102.

In some examples, browser instance 614 is transparent and authenticates the user in the foreground. FIG. 7 is an example page 700 that is displayed by merchant application 604 on a display of user device 104, with browser instance 614 being transparent. Browser instance may be displayed on page 700, but not viewable by the user. Page 700 includes a non-user selectable option 702, which is labeled “Checkout with Payment Service Provider” and corresponds to user selectable option 114 in FIG. 1 that was selected by the user. In page 700, non-user selectable option 702 is “grayed out” and is not selectable by the user. In some examples, the merchant application is displayed on a display coupled to user device 102, and an icon 704 indicating that additional processing is being performed by the user device is displayed in the merchant application. Icon 704 may indicate to the user that some processing is being performed by the user device based on the user selection of user selectable option 114 in FIG. 1. The merchant application may display icon 704 on the display of the user device, while actions are being performed by browser instance and the payment provider server to authenticate the user. In this example, the user device may continue to display page 700 while the example actions in FIG. 6 are being performed. Content may continue to be displayed on the display while the user is being authenticated by the payment service provider. Accordingly, it may appear that merchant application 604 is performing actions to process the transaction with the payment service provider and the processing is happening within the merchant application.

FIG. 8 is an example page 800 that is provided by merchant application 604 to the user. Page 800 includes the text “Thank you for your purchase! We will deliver these items to the mailing address below: 123 Main Street Washington, D.C. 22202” along with images of the items the user purchased in the transaction. Page 800 also includes a user selectable option 802, which is labeled “Back to Shopping,” that if selected provides the user with other items that the user may place into her electronic shopping cart and eventually purchase. Accordingly, the user may request to complete another transaction using the payment service provider by selecting user selectable option 114 to checkout with the payment service provider (see FIG. 1).

User device 102, façade 620, authentication platform 311, and checkout platform 627 may each include one or more processors, memories, and other appropriate components for executing instructions such as program code and/or data stored on one or more computer readable mediums to implement the various applications, data, and steps described herein. For example, such instructions may be stored in one or more computer readable media such as memories or data storage devices internal and/or external to various components of system 600, and/or accessible over network 608. Network 608 may be implemented as a single network or a combination of multiple networks. For example, in various embodiments, network 608 may include the Internet or one or more intranets, landline networks, wireless networks, and/or other appropriate types of networks.

User device 102 may be implemented using any appropriate hardware and software configured for wired and/or wireless communication over network 608. For example, in one embodiment, the user device may be implemented as a personal computer (PC), a smart phone, wearable device, laptop computer, and/or other types of computing devices capable of transmitting and/or receiving data, such as an IPAD® from APPLE® or an ANDROID® smartphone. Trademarks are the property of their respective owners.

User device 102 also may include other applications to perform functions, such as email, texting, voice and instant messaging (IM) applications that allow the user to send and receive emails, calls, and texts through network 608, as well as applications that enable the user to communicate, transfer information, make payments, and otherwise use a smart wallet through the payment service provider.

It should be understood that various actions by the user may send a user request to complete a transaction using a payment service provider to payment provider server 304 (see block 202 in FIG. 2). FIG. 9 is an example page 900 that is displayed by a merchant application on a display of user device 102. Page 900 includes content that may be controlled and provided by a merchant. In the example illustrated in FIG. 9, page 900 includes items 102 a and 102 b that are provided by the merchant and is a confirmation page that requests the user to confirm her order. Additionally, page 900 includes user selectable options that if selected by the user causes the merchant application to send a user request to complete a transaction using a payment service provider to a payment provider server. In some examples, the same merchant application that displays page 100 in FIG. 1 also displays page 900 in FIG. 9. For example, the merchant application may display page 900 in response to the user selecting user selectable option 114.

Page also includes a user selectable option 912, which is labeled “Cancel Transaction,” and a user selectable option 914, which is labeled “Confirm Payment using Payment Service Provider.” The user may select user selectable option 912 to cancel the transaction. In response to the user selecting user selectable option 912, the merchant application may remove all items from the user's electronic shopping cart. The user may then proceed to place items into her electronic shopping cart. Alternatively, the user may select user selectable option 914 to confirm payment using the payment service provider and complete the transaction. In response to the user selecting user selectable option 914, the merchant application may receive the user's request to complete a transaction using the payment service provider (see block 202 in FIG. 2). Process flow may then continue to blocks 204 and 206 in FIG. 2.

Referring now to FIG. 10, an embodiment of a network-based system 1000 for implementing one or more processes described herein is illustrated.
